I like this sollution

i like it solution :)

you're right i did not htink about it

seriously it is works ;)

my program counts well
System.out.print(LuckyNumber.isLucky(93)); false
System.out.print(LuckyNumber.isLucky(0)); true

this cata is badly made

testRandomNumbers
Log
93
0
expected:false but was:true
here is mistake, 0 should be true

i can't find solution :) ok thnaks for answer

when i pressed attemp, my program din't passed
Log
-1
eliminate_unset_bits(10100011000111000111101000011111111110000011111010101011): Expected 4294967295, found -1.

but when i created my test:
cr_assert_eq(eliminate_set_bits("01110011011101101100010110100011100111110001111110111010000"), 17179869183);
everything was ok :) something is bad with main test.

have problem because long type can't store value 17179869183
correct result = 17179869183

unsigned long i = 17179869183;
long j = 17179869183;

printf("%ld \n",(long)i); //-1
printf("%lu \n",(long)i); //4294967295

printf("%ld \n",(long)j); //-1
printf("%lu \n",(long)j); //4294967295

in which type.. can i store the result=17179869183?
